- Q:what is best for making refractory insulation for Blast furnace, hot stove.
- High dimensional insulating blanket.
- Q:What refractory materials are used in power plant
- And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)
- Q:Who knows about the criteria of fireproof and thermal insulation materials?
- 1. thermal insulation materials with A-level combustion performance: EPS sea capacity module, rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. thermal insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), phenolic aldehyde, gelatine powder polyphenyl granule,etc. 3. thermal insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc. Such A-level insulation materials are only fireproof, the thermal insulation properties are worse than that of organic XPS \\EPS materials. Currently I think that the best insulation material should be EPS sea capacity module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The thermal insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range. I hope my answers help you.
- Q:What kind of refractories do the anode baking furnace use?
- 5% volume density. 2 , The application results show that it has the energy-saving effect. 4, Withstand voltage strength. The 50MPa prebaked anode baking furnace furnace wall replaces traditional small special-shaped brick with steel fibre reinforced castable precast block: The aluminum content is 45-60%. The iron content is less than 1. I know someone uses andalusite bricks. This method, under the condition of not changing the roasting technique , has excellent resistance to CO. If there are investors, you can complete the overhaul and reconstruction work of anode baking furnace, which is still a precedent in the country. The andalusite bricks are significantly better than clay bricks. The volume density of 5% of it is 2.25. The compressive strength of 40MPa aluminum content is 60%, and the iron content is less than 1. The andalusite is more denser in the structure. Physical and chemical indicators are as following: it has a good anti-corrosive of exhaust gas Na2O. This is because its chemical composition and mineral composition are very suitable for anode baking furnace, which has long life and easy construction and other characteristics.
- Q:What are the material requirements of class A fire resistant door ?
- Refractory time should be no less than 1.5 hours.
- Q:What's the texture of refractory for the hearth of reverberatory?furnace? ?
- The long-term usage temperature of ceramic fiber is between 950-1260 degrees.
- Q:Urgently!! Refractory problems, online, etc.
- The service life of most refractory materials is a pair of contradictory effects. As a result, one aspect of the contradiction is porosity, and the other is volume density. The larger the volume density is, the smaller the porosity is and the more erosion resistant, but the thermal shock effect is very poor. The bigger the porosity is, the smaller the volume density is, the better the thermal shock effect is, but it is not resistant to erosion. More professionally, two curves should be made to find the intersection of the curves to adjust the recipe and production process
- Q:Which basic refractory is better?
- Zhengzhou Xindeyuan Refractories Co., Ltd.and Zhengzhou Rongsheng Kiln Refractories cO.,Ltd. Their basic refractories mainly refer to refractories with magnesium oxide and calcium oxide as main components what can resist errosion of basic slag, including magnesia bricks, magnesia-alumina bricks, magnesia-chrome bricks, dolomite?bricka and so on(magnesia bricks), among which magnesia bricks is the most common. Magnesia brick containing more than 80% to 85% magnesium oxide, has good resistance to basic slag and iron slag, and higher refractoriness than clay and silica brick. It is mainly used for open-hearth?furnace, oxygen-blown converter, electric furnace, ferrous metal smelting equipment and other high temperature equipments.
- Q:Could you tell me how does fire protection standard of decorative material is divided?
- Building materials can be divided into four levels according to combustion performance (non-combustible, flame retardant, flammable, flammable). According to the Code for Design on Building Fire Protection and Prevention (GBJ16-1987) (revised in 2001):, the fire risk of production or storage is divided into a, b, c, d, e classes. Divided by plate material: structure material, base layel materials and fabric; Divided by fire protecrtion type: easy to burn, difficult to burn, flame retardant, incombustible material. Material has no fire rating, only the different from the time of combustion limit. Combustion performance grade A of commonly used adornment material: granite, marble, terrazzo, cement products, concrete products, gypsum, lime products, clay products, glass, ceramic tile, Mosaic, steel and alloy. I hope my answer can help you.
- Q:How to distinguish the construction fire-proof material rating?
- Each country has its own fireproof standards, so I do not know which country you are in ? Each country has different division levels of fireproof materials, such as GB 8624, German standard DIN 4102-1, British standard BS 476, France standard NF P92-501 and so on. GB 8624 Chinese building materials and products combustion performance division levels fireproof resources network (FireTC.
